Description

CROSS REFERENCE TO RELATED APPLICATION

This application claims the benefit of U.S. patent application Ser. No. 61/766,579, which was filed on Feb. 19, 2013, and is incorporated herein by reference in its entirety.

TECHNICAL FIELD

This disclosure relates to implementations of a mount assembly for interchanging optical sights on a pistol.

BACKGROUND

Most pistols come from the factory with iron sights. Typical iron sights provided on a pistol include a front post and a rear notch which must be aligned to aim the pistol. Mounting an optical sight on a pistol offers a shooter several advantages over using iron sights alone. Optical sights provide a simple sight picture comprised of a single illuminated aiming point in place of the front post and rear notch of iron sights. In this way, a shooter's accuracy and/or speed with a pistol may improve. Further still, a shooter may be able to aim with the illuminated aiming point of an optical sight in environmental conditions that would make visual alignment of the iron sights difficult or impossible, low light conditions for example.
However, given the design of most pistols, attaching an optical sight may be difficult to do. In order to accommodate an optical sight, the slide of the pistol may need to be permanently modified in order to receive an optical sight thereon, milled for example. If the user decides to switch to a new optical sight, further modifications to the pistol may be required. In some instances, the pistol may not be suitable for further modification.

DETAILED DESCRIPTION

Implementations of a mount assembly for interchanging optical sights on a pistol are provided. In some implementations, the mount assembly comprises an adaptor plate and a pistol slide having an adaptor interface. In some implementations, the adaptor interface of the pistol slide is configured to receive an adaptor plate therein. In some implementations, an optical sight may be secured to the adaptor plate.
In some implementations, a pistol slide may be manufactured with an adaptor interface in accordance with the present disclosure. In some implementations, a pistol slide may be machined or otherwise modified to have an adaptor interface in accordance with the present disclosure thereon.
In some implementations, the adaptor interface on the pistol slide may be a dovetail. In some implementations, the adaptor interface may be any shape suitable for receiving an adaptor plate.
In some implementations, the pistol slide may include a locking tab relief. In some implementations, the locking tab relief may include a threaded opening.
In some implementations, the adaptor plate may be any shape suitable for mounting an optical sight thereon. In some implementations, the adaptor plate may be configured to fit within the ridges of a dovetail. In some implementations, a top side of the adaptor plate may include a recoil lug thereon. In some implementations, the adaptor plate may include a locking tab thereon. In some implementations, the locking tab may be configured to fit within the locking tab relief of the pistol slide. In some implementations, adaptor plates may be configured to work with a variety of optical sights without departing from the scope of the present invention.
FIG. 1 illustrates an example mount assembly 100 for interchanging optical sights on a pistol according to the present disclosure. Through the use of interchangeable adaptor plates constructed to receive optical sights thereon, a user may change the optical sight mounted on a pistol slide by changing adaptor plates. In this way, further modification to the pistol slide is not required to accommodate a variety of optical sights.
As shown in FIG. 1, in some implementations, the mount assembly 100 comprises an adaptor plate 12 and a pistol slide (e.g., pistol slide 10) having an adaptor interface 20. In some implementations, an optical sight (e.g., optical sight 16) may be secured to the adaptor plate 12.
In some implementations, a pistol slide may be manufactured with an adaptor interface 20 in accordance with the present disclosure. In some implementations, a pistol slide may be machined or otherwise modified to have an adaptor interface 20 in accordance with the present disclosure. In some implementations, the adaptor interface 20 has end walls 21 a, b and a bottom surface 9. In some implementations, the bottom 9 of the adaptor interface 20 is recessed below the top surface of the pistol slide. In this way, an optical sight attached to an adaptor plate 12 may sit lower on the handgun slide than if the optical sight was mounted on top of the handgun slide. In some implementations, the depth of the bottom 9 of the adaptor interface 20 on a handgun slide may be limited by the amount of material which may be removed and/or omitted without compromising the structural integrity of the handgun slide.
In some implementations, the adaptor interface 20 of the pistol slide 10 may be constructed to receive an adaptor plate 12 therein (see, e.g. FIG. 2). In some implementations, the walls 21 a, 21 b may be slanted at an angle relative to the bottom 9 of the adaptor interface 20. In some implementations, the ends 11 a, 11 b of the adaptor plate 12 may be slanted and configured to interface with the slanted walls 21 a, 21 b of the adaptor interface 20. In some implementations, the walls 21 a, 21 b of the adaptor interface 20 may be constructed in the form of a female portion of a dovetail joint (see, e.g., FIG. 2). In some implementations, the ends 11 a, b of the adaptor plate 12 are constructed in the form of a male portion of a dovetail joint (see, e.g., FIG. 4). In this way, when the adaptor plate 12 is inserted into the adaptor interface 20 a secure connection may be achieved (see, e.g., FIG. 2). In some implementations, the adaptor interface 20 may be any shape suitable for receiving an adaptor plate 12 therein.
In some implementations, the pistol slide 10 may include a locking tab relief 22. In some implementations, the locking tab relief 22 may be located on a side of the handgun slide 10 (see, e.g. FIG. 3). In some implementations, the locking tab relief 22 may include a threaded opening 24 therein (see, e.g., FIG. 3).
In some implementations, the adaptor plate 12 may have the general shape of a rectangle (see, e.g., FIG. 4). In some implementations, a top side of the adaptor plate 12 may have a relief 60 therein configured to receive an optical sight (e.g., optical sight 16). In some implementations, the adaptor plate 12 may be any shape suitable for mounting an optical sight thereon. In some implementations, the optical sight may have an aiming point illuminated by electricity, tritium, a light emitting chemical reaction, or a combination thereof. In some implementations, the optical sight may be an Aimpoint® Micro optical sight, a DOCTER® red dot sight, a Leupold® Deltapoint, a Trijicon RMR®, or other optical sights having a similar foot print that are currently known or developed in the future.
In some implementations, the adaptor plate 12 may be configured to fit within the ridges of a dovetail joint (see, e.g. FIG. 2). In some implementations, the adaptor plate 12 may include one or more openings 13 therethrough (see, e.g. FIG. 4). In some implementations, the top side of the adaptor plate 12 may include a recoil lug 55 thereon. In this way, an attached optical sight may be prevented from sliding back and forth due to the incidental vibrations associated with the discharge of a pistol.
In some implementations, the adaptor plate 12 may include a locking tab 26 thereon. In some implementations, the locking tab 12 may extend from the bottom of the adaptor plate 12. In some implementations, the locking tab 26 may be configured to be received within the locking tab relief 22 of the pistol slide 10. In some implementations, the locking tab 26 may include an opening 28 therethrough.
To secure the optical sight 16 to the adaptor plate 12, the optical sight 16 may be oriented so that the openings 13 of the adaptor plate 12 are aligned with threaded openings located on a bottom side of the optical sight 16. Screws 18 are then inserted through the openings 13 of the adaptor plate 12 from a bottom side thereof and threadedly secured to the optical sight 16.
To remove the optical sight 16 from the adaptor plate 12, the above steps are performed in reverse.
To secure the adaptor plate 12 to a pistol slide 10 constructed in accordance with the present disclosure, the adaptor plate 12 may be inserted into the dovetail portion of the adaptor interface 20. The adaptor plate 12 will come to rest with the locking tab 26 seated within the locking tab relief 22 located on the pistol slide 10 (see, e.g., FIG. 2). A screw 14 is then inserted through the opening 28 of the locking tab 26 and threadedly secured into the threaded opening 24 of the locking tab 26 relief.
In some implementations, an additional dovetail 40 may be provided on the pistol slide 10 (see, e.g., FIG. 3). In some implementations, the dovetail 40 is located between the ejection port 45 and adaptor interface 20 of the pistol slide 10. In some implementations, the dovetail 40 may be constructed to receive a notch sight (notch sight 50) (see, e.g., FIG. 1). In some implementations, the dovetail 40 may be constructed to receive any rear sight suitable for use with a pistol. In this way, iron sights may be used in conjunction with some implementations of the mount assembly 100 disclosed herein.
In some implementations, the adaptor plate 12 of the mount assembly 100 may sit low enough within the adaptor interface 20 to allow a user to align the iron sights of a pistol while looking through an optical sight 16 mounted on an adaptor plate 12.
